In a galaxy ruled by warlords, guilds, and ancient tech cults, Kai Zareth is just another debt-ridden scavenger—until a legendary system descends upon him.“One Trader per 10,000 light years. One chance to rise.”Selected by the Cosmic Trade Nexus, Kai becomes the sole wielder of the Galactic Exchange System, a multidimensional platform that allows him to buy and sell across parallel worlds, forgotten realms, and alien civilizations.With only 12 hours to complete his first trade—or lose everything—Kai scrambles to make deals in a universe where information is power and one wrong barter could cost your life.From selling enchanted goblin toothbrushes in toxic slums to outwitting rival system users and forging alliances with forgotten races, Kai must build his empire item by item, realm by realm.But in a galaxy where traders kill for profit and system users are hunted like prey, being the Merchant Sovereign might be a bigger curse than a blessing.
